Invasion of Iran - April 6th?

This article at Government Dirt claims that Moscow sources say that the US will invade Iran on April 6th at 4AM local time. Friday April 6th is a holiday in Iran.

Of special note here is what the article states regarding a recently passed Democrat bill and what was removed:
This attack is sanctioned by the Democratic leadership of the House of Representatives because they removed language from the just-passed Iraq supplemental military appropriations bill that would have demanded that Bush come to Congress before launching an attack on Iran.

This means that, contrary to what I previously thought, Bush can order an invasion at the drop of a hat.

Oil prices will jump, so will the price of gold, and tensions will rise dramatically around the world. Prepare for the worst.
Doom.
